[0057] Reference Figures 1 to 10In this embodiment, the first positioning slots 341 on the access carrier plate 34 are arranged at intervals in the horizontal direction, so a material tray moving channel along the longitudinal direction is formed between the first fixed limiting plate 36 and the first movable limiting plate 39; the setting of the vertical cylinder 471 can make the positioning roller 49 descend, providing a moving channel for the material tray along the longitudinal direction; the vertical drive assembly 35 is used to control the lifting and lowering of the access carrier plate 34, and the third horizontal drive assembly 42 is used to control the translation of the receiving carrier plate 433, so that the position of the dial plate 54 can be easily adjusted to avoid interference; the fourth horizontal drive assembly 51 controls the dial plate 54 to move in the longitudinal direction, so that the empty material tray on the access carrier plate 34 can be transferred to the receiving carrier plate 433, and the full material tray on the receiving carrier plate 433 can also be transferred to the access carrier plate 34; In this embodiment, both the material tray storage and retrieval mechanism 3 and the material receiving mechanism 4 use cylinders to clamp the material trays, and use a dial plate 54 to push the material trays for transfer, so both the storage and retrieval carrier 34 and the material receiving carrier 433 are provided with adjustable structures to be compatible with material trays of different sizes and specifications, and a plurality of dial protrusions 541 are also provided on the dial plate 54. Such a compatible method has the advantages of simple structure, convenient operation, and low production cost; in other optional embodiments, other methods can also be used to fix the material trays on the storage and retrieval carrier 34 or the material receiving carrier 433, such as vacuum adsorption, etc., or other methods can be used to transfer the material trays, such as clamps, etc., to achieve compatibility with material trays of different sizes and specifications. Of course, the method in this embodiment is more preferred.
